Verification of details of AD2 scope measurements pane: Value & Average

[vkristof]

I'm using the AD2 scope (with Waveformsrunning on W10) to measure low frequency signals (example Timebase 100ms/div) and am specifically interested in the AC RMS and DC RMS calculations AND Average Column and how they interact with the Single and Run buttons

 

I'm assuming the Value calculations are run once (& displayed) once the scope buffer (8k or 16k) is filled, is that correct?

I'm also further assuming that the Average column is then a running average (assuming the "Run" button is clicked) of the Values column as the scope buffer is filled, Value is calculated, etc.

So, for example, if the scope Run had filled the buffer twice, the Average column would just be the average of the two sets of values that had been calculated, is that correct?

 

Thank you.

Hi @vkristof,

I wanted to let you know that you posted your question in the correct section of the Forum; I don't know the specific answers to your question (or at least wasn't able to definitively find it looking through the built-in WaveForms documentation in Help->Browse) but the engineer who is much more familiar with the WaveForms software will be able to see and respond to your question. They're in a different timezone though, so it might be until Monday when they get a chance to read your question.

Thanks,
JColvin

Hi @vkristof

Yes.
The Voltmeter and Logger tools basically perform scan capture in background and at the specified rate (Update time) calculate the DC, AC/DCRMS
Just like performing separate captures on full device buffer size (at sample rate of buffer_size/update_time) for each set of value.
With single just one set of value is calculated on device buffer size.
